Which setting have you used? You can hear him if you use "all audio" instead of "Chat" but then overall volume is much lower. Currently it's a trade off. It's something i have raised in the WMD community as well as in here previously.

An option in game is what we need. Many other games do it. I think its about the worst design choice Sony made when developing the ps4. Just remove all features for it in all games. It's useless.
